## Abstract

EPA is taking direct final action on the latest revision to the Pennsylvania State Implementation Plan (SIP) consisting of the plan the Commonwealth will use to conduct the ongoing evaluation of its enhanced inspection and maintenance (I/M) program. With the submission of this program evaluation plan, Pennsylvania has remedied all conditions that EPA had placed upon approval of the Commonwealth's enhanced I/M program. Therefore, EPA is today converting its conditional approval of Pennsylvania's enhanced I/M program SIP revisions to full approval, in accordance with the requirements of the Clean Air Act.
